INVENII'OR BY ATTORNEYS Patented May 30, 1939 UNITED STATES PATENT OFFICE OPHTHALIWIC MOUNTING of Pennsylvania Application March 2, 1937, Serial No. 128,608

2 Claims.

This invention relates to eye-glass mountings comprising a pair of lens-clamping framings and a connecting bridge member, of the type indicated in my prior Patent No. 1,971,055 issued 5 April 21, 1934; the invention consisting in the improved combination of the framings and bridge member hereinafter fully described in connection with the accompanying drawing and specifically pointed out in the subjoined claims, and the essential purposes being to advantageously simplify and improve both the construction and appearance of the mounting,

Fig. l is a rear view of a bridge-connected eyeglass framing embodying the invention in the simple clip-on type of mounting illustrated in my prior patent referred to, without showing of nose contacting or head-band attaching means which may be provided as usual when desired; one end of the bridge member being shown disconnected from its framed lens.

Fig. 2 shows a disconnected lens with the positioned framing on it; the portion of the lensframing ring which carries the overlying clamping ear being shown as less sharply bent than in the Fig. 1 showing as hereinafter referred to.

Fig. 3 is a separate plan view of the bridge member; and Fig. 4 is a fragmentary plan view of the disconnected clamping ears of the Fig. 2

framing.

Each open-ring eye-wire framing I encircles the rim of a lens I2 as usual; and it is formed with opposite-end perforated clamping ears I3, I4 between which a perforated end portion I5 of the connecting bridge member I5 is engaged by a connecting pin or eyelet I6. This connection of framing ears to a bridge member is broadly old, and my prior patent referred to also provides a forked extension of each perforated bridge end L5 for use in insuring a rigid connection of the parts. In the improved arrangement of the ears and the engaging bridge ends now set forth, however, the combining of the parts is advantageously effected both as to the satisfactoriness of their connection and as to the 45 completed appearance of the device, so as to give important novelty to the specific construction and arrangement of the necessarily simple elements.

As shown in the drawing, the opposite-end clamping ears I3, I4 of each framing I0 are overlapped upon the enclosed lens in spacedapart parallel relation, close to and substantially tangential to the rim of the lens; the only required deviation of the ears from the normal line of the enclosing ring being provided first by a bending I0 of the eye-wire adjacent the underlying ears M, to raise the latter slightly above the lens rim for accommodation of the inner end of the eyelet or pin, as shown; and

second by an upward reverse bending of the eye wire adjacent the overlying ear I3, as shown at I 0 in Fig. 1 and with somewhat different angling at F Fig. 2.

The connecting end portions I 5, I 5 of the bridge member I5, are maintained in alinement with the body of the latter as shown, no bending thereof being required; and when inserted between and connected to the spaced-apart clamping ears of the respective framings their forked ends I5 engage the upward bends Ii} or In -of the eye-wire rings so as to provide a rigid connection. The thinness of the horizontally overlapped ears I3, I4 and of the engaged bridge end l5 forms only a slight bulge upon the rim of each lens, and the connecting ends of the bridge member lie closely tangent to it and immovably engaged by the upward bends If! and II] of the eye wires. These slight bendings of the eye-wire give a resilient yield to it which facilitates snug fitting upon the encircled lenses; and satisfactory fitting to moderately varying sizes of lenses may be secured by merely varying the bendings of the eye wires IE and Iii as indicated in Figs. 1 and 2 respectively, so as to dispense with the slack take-up loops which are commonly formed in it so as to serve also for head band connections when these are required.

What I claim is:

1. An eye-glass mounting comprising a pair of open-ring eye-wire lens framings each having perforated clamping-ears at the meeting ends thereof, and a connecting bridge member having opposite perforated end portions with forked extensions; the clamping-ears of each framing being extended in opposite directions and overlapped tangentially of its encircled lens in spacedapart parallel relation, and having one perforated end of said bridge member extending between and secured to the spaced-apart ears with the forked end thereof engaging the eye wire adjacent the overlying ear.

2. An eye-glass mounting comprising a pair of open-ring eye-wire lens framings each having perforated clamping-ears at the meeting ends thereof, and a connecting bridge member having opposite perforated end portions with forked extensions; the clamping-ears of each framing being extended in opposed directions and overlapped tangentially of its encircled lens in spacedapart parallel relation, and having one perforated end of said bridge member extending between and secured to the spaced-apart ears'with the forked end thereof engaging the eye-wire adjacent the overlying ear; said eye-wires having variable outwardly-bent portions connecting said clamping ears thereto so as to provide for variations in the size of the framed lens.
